Introduction of DMLS
Direct Metal Laser Melting (DMLS), also known as DMP technology, is widely used in the metal 3D printing field. The principle of DMLS technology is similar to SLM. Through laser sintering of metal powder material, when a layer of sintering is completed, then a new layer of powder is transported until the entire part is finished.

CD BioSciences is a trusted high-tech company providing 3D printing products and services to a wide range of industries. CD BioSciences offers integrated metal printing solutions with high-quality metal materials, as well as specialized metal printing technology.
The parts printed by DMLS technology have properties comparable to those of casting or cutting methods, and the entire process does not require metal machine tools or molds. The technical work steps of DMLS provided by CD BioSciences are as follows.
- Design and build a 3D model through CAD software on the computer.
- Transform the CAD model into a cross-section of the component.
- The 3D printer laid the metal powder flat.
- Under the control of the 3D model, the high-precision laser sinters local metal powder and attaches it to the front layer.
- Build thin metal layers one by one.
- Generate dense metal entity parts.
Note: This process does not require any adhesive or glue.
Features of DMLS
- The DMLS technology provided by CD BioSciences uses a laser with high energy, high precision, and stable characteristics, and it is crucial for the performance of final printed products.
- Because DMLS directly sintered metal powder, the surface of the printed part will be a little rough, but with only a little polishing, you can get a smooth appearance.
- The printer works in an inertial area of nitrogen or mucus protection to prevent metals from being oxidized at high temperatures to ensure that parts have a dense and uniform material structure.
- Selecting different metal materials and adjusting technical parameters can greatly improve the performance of parts with great differences.
Materials for DMLS
DMLS technology uses a wide range of materials with various properties and surface characteristics to meet the specific needs of different conditions. DMLS technology can be used for almost all metal alloy materials.
Applications of DMLS
DMLS technology can directly manufacture metal parts with excellent mechanical and thermal performance, and can print parts with complex geometry and internal structure in a relatively short time. Therefore, DMLS technology is widely used in high-end precision parts manufacturing and other fields.
- Aerospace industries
- Automobile industries
- Metallurgy
- Medical instruments
- Petrochemical industry
- Ship
Advantages of DMLS
- The structure of the parts is completely dense
- The microstructure is uniform, the grains are small, and non-porous
- The density is greater than the theoretical density
- No mold is required
- Shape complex metal parts of any desired shape;
- High material utilization rate
- Increase the rate
- Greatly increased freedom
- Easy to control and design
DMLS is a rapidly growing and powerful metal 3D printing technology. It often uses alloy powder materials to create complex, strong and dense metal parts. CD BioSciences provides specialized DMLS technology to support the production of critical metal components with unrestricted, high-precision, and high performance in various industries.
